John Kacur 6432e734c9 sony_pi: Remove the BKL from open and ioctl ...

The BKL is in this function because of the BKL pushdown (see commit
f8f2c79d59)

It is not needed here because the mutex_lock sonypi_device.lock provides
the necessary locking.

sonypi_misc_ioctl can be converted to unlocked ioctls since it relies on
its own locking (the mutex sonypi_device.lock) and not the bkl

Document that llseek is not needed by explictly setting it to no_llseek
